REFUSE AND GARBAGE INCINERATOR.

Application filed January 20, 1926. Serial Ito 82,511.

My present invention relates generall to improved apparatus may consist of any derefuse, trash and garbage burners w ich sired number of units, each unit preferably may also be used to a considerable extent in comprising a pair of circular furnaces of the incineration of these mixed materials, similar construction, each having an annu- 5 and my primary object is the-provision of lar wall rising around a furnace floor 11 an apparatus especially adapted to the burnand surmounted by a dome-shaped top 12, ing of bulky trash and refuse more particuthe latter preferably covered by a layer of larly in those localities where refuse for fuel asbestos 13 and having an upper central is rarely, if ever, used, and where as a conopening 14 into which the lower end of a 10 sequence bulky materials are commonly charging chute 15 opens. This chute is burned as a means of disposal. A further preferably disposed vertically above the object is the provision of an apparatus of furnace with its upper end opening through this type which may be easily and quickly a charging floor 16 extending continuousl Started and which, after starting, will be abovethe two furnaces and the space there- 15 continuously automatic in its action. between, the upper ends of the two char A still further object of my invention is ing chutes 15 being normally closed by doors the provision of a trash and garbage burner or manhole covers 17, removal of which perinto which the trash or refuse may be indismits of readily dumping the trash and refcriminately dumped, with or without garuse directly into the two furnaces and onto 20 bage, and which will effectively and autothe central portions of their floors 11.

Communication is had from these and provides for continuous complete comoutlets indicated at'21, between the furnaces bustion and for the ready easy cleaning and the stack flue 20, through checkered thereof to maintain the furnace as a whole walls 22, the presence of which avoids the at maximum efliciency. danger of large unburned portions of the In the accompanying drawings which ilcharge finding their way into the stack flue lustrate my present invention and form a 20, although as will be presently seen, this 4 part of this specification: stack in itself forms a large combustion Figure 1 is a front elevation of my imchamber for the complete consumption of proved apparatus, any prevlously unburned portions of the Figure 2 is a vertical cross section taken charge, and is for this reason, preferably therethrough on the center line of the furprovided in its length between its end oom- 45 naces, municating atopposite sides with the two Figure 3 is a horizontal section therefurnaces and its opposite end connecting to through taken on a line above the grates of any suitable stack (not shown), with draft the furnaces, controlling means including bafiies 24 and Figure 4 is a horizontal section taken 25 spaced throughout the length of the flue therethrough on a line below the grates of and alternately upstanding from its lower the furnaces, and, portion and depending from its top in the Figure 5 is a vertical longitudinal section manner most plainly seen in Figure 5. taken centrally through a portion of the In addition to these features, the stack stack flue. flue 20 is preferably provided'at its end and Referring now to these figures, and paralong its sides with clean out .o enings 26 ticularly to Figures 1 to 3 inclusive, my normally covered by doors and affording ready access to the flue in order to maintain the same in a clean condition and in this way avoid any interference with the draft.

It will be noted from Figs. 2 and 3 in particular that the floor 11 of each of the furnaces has an elevated fiat area 11 adjacent to its outlet opening 21 and that around this flat area for substantially its entire space, the floor is inclined downwardly and outwardly toward and to the furnace wall, and is provided in its inclined portion with a series of openings covered by main radial grates 27 and small grates 27 alternating with the main grates. Each of the grates 27 and 27 is arranged over and above an ash pit 28 below the base 11, the several ash pits being divided by walls 29 as shown in Figure 4 through which a series of openings 30 provide for communication between the several ash pits below the main grates 27 and a lower central air distributing chamber 31, the latter located immediately below the central portion of the floor 11. Into each of the air distributing chambers 31 a forced air supply fine 32 opens, this flue extending beneath a portion of the floor 11 of the furnace as well as longitudinally along and within a portion of the stack fine 20, the outer end of such flue connecting with a force feed fan and its casing 33 which in action directs a continuous supply of air into the respective chamber 31. The fan 33 it will be noted takes in comparatively cool air. This air is in its passage through the air supply 32, especially along and with in the stack flue 20, is heated to a considerable extent, and thus when forced into the chamber 3]. for distribution through the openings 30 into the spaces below the grates, is in effective condition to materially assist in the combustion within the furnace.

The severalash pits 28 are provided with clean out openings 34 through the furnace wall, normally covered by doors 35, and each furnace also has through its walls openings 36 opposite to and above the several grates, normally closed by doors 37, for the purpose of charging the furnace in the first instance with fuel when it is started, although it is to be understood that instead of charging the fuel into the furnace above the grates, oil burners may be employed through the openings 36 as generally indicated at 38 in Figs. 1 and 2 to be fed through feed lines 39 from overhead tanks 40.

In action, the trash and refuse, with and without garbage, is dumped directly through the charging chutes 15 onto the central portions of the furnace floors where this material pyramids so that a gradual continuous feed is thereafter insured onto the several grates. After igitation of this material in the first instance, the action is continuous and automatic and no further charging of fuel or burning of oil burners is needed through the openings 36.- It is of course necessary to charge the furnace sufiiciently to keep them going, with the material to be consumed, and it is necessary to clean out the ash pits through the lower openings 3i and to clean out the draft flue from time to time through the openings 26.

An apparatus constructed in accordance with my invention will be especially effective and efiicient in those continuously warm climates where refuse fuel is rarely, if ever, used, and where bulky materials, large boxes, packing cases, and the like are ordinarily burned as a means of disposal, this furnace being especially efficient in its continuous and automatic consumption of large bulky refuse and-trash.

I claim 1. A trash, refuse and garbage burner including a furnace having a wall forming therein a furnace chamber and provided with a side outlet for the products of co1n bustion from said chamber, a floor forming the bottom of the chamber having an elevated portion adjacent to the said side outlet and having a downwardly inclined por tion around said elevated-portion and between the latter and the furnace wall, a stack flue with which the side outlet co1n municates, a series of grates in the said in clined portion of the floor, means for supplying air upwardly through said grates, including an air distribution chamber below the floor, and an air supply flue communi-' eating with said distributing chamber and extending along, and subject to the heating influence of the stack flue, said furnace having an upper central opening and charging means in communication with said opening.

2. A trash, refuse and garbage burner consisting of a furnace having a surrounding wall provided with a side outlet, a floor having an elevated fiat portion adjacent to the said side outlet and having its remaining portions inclined downwardly and outwardly from said flat portion to the furnace wall, a series of grates disposed radially in the inclined portion of the floor. each having an ash pit below the level of the floor, said furnace having an air distributing chamber disposed below the central portion of the floor and in communication with the ash pits of certain of the grates, a stack flue into which the side outlet of the furnace wall opens, and means to supply air to the said air distributing chamber including an air supply fine having a portion thereof extending along and within the stack fine, the said air supply flue entering the furnace below the elevated flat portion of the floor.
